Adding Boost to a Bolt on Stock Programing Truck.

[Darkbloodmon]

Not looking to do anything immediately, but just asking since I don't know. I've still got issues to work out with my clutch.

I wasn't encouraging a scat pack Charger to do stupid things with my down shifting one night coming back from work; but I did realize how slow I am for the amount of time, effort, and money I've thrown at this truck (ongoing), not that I'm trying to get crazy but I was wondering what I could expect by adding more boost to my setup without tuning. I do have a boost, rail pressure, fuel pressure, EGT, and Trans temp gauge.

Stock Freshly blueprinted HE341 from Turbo Resource, Studded manifold, studded head, Mishimoto 3.5" intercooler - pipes - boots - CT clamps, S&B intake, BBI stage .1s, and a 4" AFE Saturn 4s Turbo back exhaust system. I'm covered on fuel with a Fass 95 and S&S Super Sport 6.7 CP3.

Currently I cap at 25psi, EGTs unloaded are cool 5-600 at highway speeds, 3-400 on the street just putting around.

Truck is an early 03 HO 305/555.

Thoughts on adding boost? EGTs? MPGs? Issues? Running Condition?

Why no tunes? Boost needs fuel. Your stock everything truck will wake up with a tune/programmer, with no other mod.

I still have my TST for sale that is for a 03-04.5 305/555 truck... It woke up my 04 and was quite nice running around and towing with no smoke / haze. I was running around 350/700 (level 4/3) with basically stock engine (could do more with engine set up like yours). PM me if you want to or are interested in it as I literally have no use for it anymore. It also has gauges integrated, a cool down timer, and user adjustable egt temp limits built in, I think boost was set to 32PSI max, but I'd have to check, its an adjustable elbow for the signal line to the waste gate.

Boost by it's self will only lower EGT's. More boost allows for more fuel while keeping EGT's in check. Take bcbender up on his offer. More fuel can spin the turbo fast and create more boost. It is a balancing act. On the 24V one needed a boost fooler or the ECU would defuel, not sure on the CR engines.

Lots of mods for stock fueling.

What are your power adding plans down the road?

Adding boost won’t do anything for power, just let you run cooler WOT. That turbo can be turned up to about 32psi before it gets past its map. It will take an adjustable boost elbow and a boost fooler.

I might have misunderstood, but I think this is what he has in mind. That his truck is mostly stock now?

It’s what it sounds like, but that’s a lot of cash on stuff that’s not needed for 305/555 so the parts tell me has has other plans but who knows.

Yes, that's why I was wondering about just a tune/programmer. Seems like a lot of expense unless he just wants it.

Sorry for the late reply, wrote the initial post after a 12hr shift(AAA), pulled an 11hr today.

Why no tunes? Boost needs fuel.

No ready for tuning yet, I still have ongoing clutch/transmission issues. But yes; boost needs fuel, more fuel makes more boost thus tuning is needed to make the best use of it. Air is free was my frame of thought and I was wondering on my current setup when more boost would reach a point of diminishing returns.

At some point when I'm 100% on the loose ends I'd like to aim for 5/9

It will take an adjustable boost elbow and a boost fooler.

That's what I was considering, instead of an elbow I was looking at a manual boost controller.

PM me if you want to or are interested in it as I literally have no use for it anymore.

I may take you up on that after I figure out my remaining loose ends and do some reading up on it. Ideally I'd like to get custom tuning done for mpg.

For clarification all the mods listed are current bolt-ons I've already installed. The only thing on my truck stock is the ECU programing, and engine internals.

Go with an adjustable boost elbow, they do the same thing for 1/10th the price. It’s not something you need to adjust after it’s set.

You don't think i'll need the adjustability for fine tuning down the road? I was thinking when I'm set for tuning it'd be a nice feature to dial in boost for a tune(s) rather than crawling under and reaching up to adjust the elbow screw each time.

Nah, not for the price difference. Set it at 32-35 psi and forget about it.

I'll take your word for it, less lines and clutter running across the engine bay the better. Any issue or cause for concern adding that amount of boost to my current setup?

You will most likely need a boost fooler of some sort. Tuner etc.

None, if it will build it on stock fuel.

You will need a boost fooler thou.

To many concerns from your side, run 35 and be happy.
The engine can take way more than that and last.

For that, not a single hardware change would have been needed aside from the boost elbow. Myself I just have a Smarty and that does the whole job. Commonrail TD is so easy to tune compared to everything we had before - and the Cummins can take it easily.

I am in the learning mode here, so the CR unlike the 24V will NOT defuel if boost is raised beyond what it expects?

It does, which is what Ozy is saying. Use a boost fooler or a tuner.

CR needs either a boost fooler or tuning to not limit the boost.

Some tuning differences 03-04 vs 04.5-07 vs 6.7.

 

[NIsaacs]

I think what SnowKing was referring to, is, OZ only said boost elbow no mention of boost fooler. It requires both.

On the hardware side that is correct, just just single boost elbow.

I guess I don’t count the fooler as hardware.
